A Note from CJ
My secret to perfect Cacio e Pepe EVERYTIME!

I have made Cacio e Pepe many times and I discovered one key tip that has helped me make it perfectly. Are you ready? Your pasta water needs to be cooled slightly to 150 degrees Fahrenheit or 70 degrees Celsius BEFORE mixing it into the sauce. Boiled pasta water is oftentimes TOO HOT – which results in the sauce becoming clumpy. A thermometer will be super helpful for this!
If you love Roman pastas like I do, make sure to try my Carbonara, Bucatini all’Amatriciana, and Pasta alla Gricia! Other favorite pastas are authentic Fettucine Alfredo, Linguine with Clams and Pasta al Limone!
It’s so easy to make, but yet very hard to master it. You are the only chef who mentioned the water temperature. Thanks!
Ingredient Tips
- Spaghetti: Cacio e Pepe is traditionally made with some kind of long pasta (noodle); I like to use spaghetti but I’ve also seen it with bucatini, linguine, fettuccine, or even short tubular pasta like rigatoni or mezze rigatoni. You can use either dry or fresh pasta – if using dry pasta, try bronze-cut pasta, which will cling to the sauce better!
- Pecorino Romano Cheese: I like to use a microplane to finely grate the cheese. I don’t recommend using pre-grated cheese, as they are usually coated with preservatives to keep the shreds from melting and clumping together, which is not ideal for emulisfying the sauce. You can substitute parmesan reggiano for the pecorino but you may need to add more salt to taste (as parmesan reggiano is less salty than pecorino.)
- Whole Black Peppercorns: I recommend dry toasting the whole black peppercorns before grinding them – dry toasting enriches the aroma and brings an extra layer of smokiness and spiciness that will truly enhance your Cacio e Pepe!
How to Make Authentic Cacio e Pepe
Toast black peppercorns, grate the cheese, and cook the pasta: First, toast the black peppercorns in a pan until fragrant over medium high heat until fragrant. Turn the heat off, then coarsely grind the peppercorns in a mortar before returning them to the pan. Finely grate Pecorino cheese with a microplane and add it to the pepper once the pan is cool to the touch. Meanwhile, cook pasta until al dente, reserving a cup of starchy pasta water halfway through the cooking process and allowing it to cool to about 150°F (70°C).
Form the Cacio e Pepe sauce and finish the pasta: To form the sauce, gradually add the cooled pasta water to the pan with ground pepper and cheese, mixing vigorously with the cheese and pepper until smooth and emulsified. Drain and slightly cool the pasta before combining it with the sauce to prevent clumping, then toss until well-coated. If needed, adjust the consistency by adding more pasta water, and finish by serving the Cacio e Pepe in warmed bowls.

Equipment
Ingredients
- 8 oz spaghetti, dried pasta weight
- 2 oz pecorino cheese, grated
- 1 cup reserved pasta water, cooled to 150F (70C), used as needed to achieve an emulsified sauce in step 3
- 1/2 tbsp whole black peppercorn
Instructions
- Toast whole peppercorns over medium high heat for 2-3 minutes until the peppercorns are toasted and fragrant. Transfer to a pepper grinder or mortar and pestle and grind to a medium coarse grind. Add back to your pan with the heat off.
- Cook your spaghetti (or pasta of choice) in lightly salted water. 2 minutes before the pasta is done, reserve 1 cup of pasta water and set on the counter to let cool to about 150F or 70C – this is the key to avoiding lumpy cheese! Adding pasta water straight from the pot is much too hot.
- While the heat is off and the pan is cool to the touch, add the grated cheese to the peppercorns along with a 1/4 cup of the cooled pasta water at a time, stirring until you get a loose but emulsified sauce.
- Add your drained pasta and mix vigorously. At this point your pasta should start to absorb the sauce, but add additional pasta water and mix if the sauce is too thick. Continue mixing until you achieve the correct consistency (refer to video). Serve immediately into warmed bowls and enjoy!

Looks like an easy recipe. My last attempt ended in clumps, so I was excited to try the cooled water tip.
Posting the correct video would help – the linked one is for shrimp, not cacio e pepe. Also, you stress the importance of cooling the water, but only mention cooling the pasta in passing. I didn’t think about the hot pasta and my smooth sauce turned to clumps… so sad.
I love pepper but 1/2T was too much – perhaps toast that much but start with 1/2 t of ground pepper (after toasting and grinding), and then add more pepper to taste, vs. starting with all the pepper in the pan.
Ingredients often die in the learning process, but I’m sad to have wasted 6 oz of bucatini that I brought back from Italy and a bunch of expensive pecorino. Oh well, I know to practice more next time!
Hi Anne! I really appreciate the feedback. I do like a lot of black pepper so I can definitely agree with the less first approach. For the video, the Cacio e Pepe video plays first then after that playthrough it auto plays other related videos, so if you need to watch the original video again, just refresh the page! Thanks again for taking the time to leave a helpful comment!
